Elevator long-object checking device

A long-object checking device that detects an abnormality of a long object wound and hung around a grooved wheel in a hoistway in which a car of an elevator runs, the long-object checking device comprising:

• a camera that images one or both of a position above and a position below the car so that an imaged range includes the long object and the grooved wheel;
• and
• processing circuitry
• to perform an image processing process to detect a part rendering the long object from an image taken by the camera, and
• to judge whether the abnormality of the long object exists or is absent, on a basis of a condition of the long object detected by the processing circuitry, wherein
• the processing circuitry performs an image processing process to detect a part rendering the grooved wheel from the image taken by the camera;
• and
• the processing circuitry performs an image processing process to detect the part rendering the long object from the image taken by the camera, by referring to a position of the part rendering the grooved wheel detected by the processing circuitry.
